 Introduction

When dealing with more advanced piping projects, there might come a time where more sophisticated processes are applied. Some of the piping materials have to be welded and joined together and one of the ways to achieve this is by electrofusion. This method is used to join various types of pipes such as MDPE, HDPE as well as other types of plastic grade material pipes. For those who are new to electrofusion, this process uses a special fitting that have a specialised built-in electric heating components used to join pipes together.Overall, it is perhaps one of the most idealistic ways to join two ends of a pipe together in a simple, fast, cheap, and reliable way.

 Gas fittings & jointing

How this process works is relatively simple as the pipes are cleaned thoroughly first before they are joined. They are then placed into the electrofusion fitting with a clamp and an electrical voltage of around 40V is used for a short time. The coils inside the fitting will heat up and melt the inside of the fitting and the outside of the pipe wall which then creates the welding process. The pipe is then left to cool which creates a very strong and uniformed joint. It is basically a heating process which melts plastic and wields it together again to form one uniformly strong and perfect joint.

When applying electrofusion gas fittings, it is imperative that the ability of the individual who is applying this method is skilled enough. The person needs to have prior training as this type of welding process needs to be done correctly especially if it is later to be used for applications such as gas. As with many installations, there are probable risks that can and will occur if safety precautions are not taken beforehand. Leaks may occur in the electrofusion gas fittings and can prove catastrophic.However by using robust quality tools and utilities, this factor can be safely eliminated. Those without proper training should not at all attempt to install electrofusion gas fittings without prior practice, especially if the utilisation during that point in time is permanent.

Applications

A lot of industries that deal with water and wastewater treatment will most likely use PE pipes and electrofusion gas fittings as a means to weld the pipes together. The utilisation of water, gas and sewage pipes are ideal for electrofusion use. A company who might be in the gas industry might prefer to use this application as a quick and flexible way to install or repair old and damaged parts. In addition, the simplicity of this method enables companies to save a lot of money in maintenance and installation costs. This then further enables companies to rely solely on PE formed pipes over the metal graded materials which are heavy and more expensive to maintain.

The important thing about using this method is that the process has to be carried out correctly. This means that the pipe surfaces and electrofusion fitting has to be cleaned thoroughly before use. In addition, the pipes have to be aligned correctly (straight) and the human welder has to have the experience in operating the fitting tool which all greatly impacts towards the risk of leaking. If installed correctly by competent hands, the fittings can last for up to a minimum 50 years.

Conclusion

Without a doubt, there are many great advantages that can be had by utilising electrofusion. A strong and uniformed joint can be achieved and can last a very long time. However, achieving this result requires the skilful operation of a handler as well as using the quality equipment for it. If done right, this practical method of welding pipes will be beneficial in terms of cost effectiveness, as well as time saving measures when it comes to its application. This method is an ideal and practical solution for those who are in the water and gas industry, or those who utilise these elements.
